// ArrayListExample
import java.util.ArrayList;
import java.util.List;

// Main class containing the entry point of the program
public class Main {
    public static void main(String[] args) {
        // Step 1: Create an ArrayList to store String elements
        List<String> fruits = new ArrayList<>();
        System.out.println("Initial fruit list: " + fruits);

        // Step 2: Add elements to the ArrayList
        fruits.add("Apple");
        fruits.add("Banana");
        fruits.add("Cherry");
        System.out.println("After adding fruits: " + fruits);

        // Step 3: Access elements by index
        String firstFruit = fruits.get(0);
        System.out.println("First fruit: " + firstFruit);

        // Step 4: Check if an element exists
        boolean hasBanana = fruits.contains("Banana");
        System.out.println("Contains Banana? " + hasBanana);

        // Step 5: Remove an element by value or index
        fruits.remove("Banana"); // Removes "Banana"
        System.out.println("After removing Banana: " + fruits);

        // Step 6: Get the size of the ArrayList
        int numberOfFruits = fruits.size();
        System.out.println("Number of fruits: " + numberOfFruits);
    }
